# --description--
|
|
|
|
Just as we can build a string over multiple lines out of string <dfn>literals</dfn>, we can also append variables to a string using the plus equals (`+=`) operator.
|
|
|
|
Example:
|
|
|
|
```js
|
|
const anAdjective = "awesome!";
|
|
let ourStr = "freeCodeCamp is ";
|
|
ourStr += anAdjective;
|
|
```
|
|
|
|
`ourStr` would have the value `freeCodeCamp is awesome!`.
|
|
|
|
# --instructions--
|
|
|
|
Set `someAdjective` to a string of at least 3 characters and append it to `myStr` using the `+=` operator.
|
|
|
|
# --hints--
|
|
|
|
`someAdjective` should be set to a string at least 3 characters long.
|
|
|
|
```js
|
|
assert(typeof someAdjective !== 'undefined' && someAdjective.length > 2);
|
|
```
|
|
|
|
You should append `someAdjective` to `myStr` using the `+=` operator.
|
|
|
|
```js
|
|
assert(__helpers.removeJSComments(code).match(/myStr\s*\+=\s*someAdjective\s*/).length > 0);
|
|
```
|

## --seed-contents--
|
|
|
|
```js
|
|
// Change code below this line
|
|
const someAdjective = "";
|
|
let myStr = "Learning to code is ";
|
|
```
|
|
|
|
# --solutions--
|
|
|
|
```js
|
|
const someAdjective = "neat";
|
|
let myStr = "Learning to code is ";
|
|
myStr += someAdjective;
|
|
```
